0.47ohmWhat source resistance will be using on the fets?
Thanks
If you buy 4 tubes that are all from the same manufacturing batch you should be fine.
Tell Digikey/Mouser, this is a requirement for the sale.
They will make sure you get what you ask for.
If you are nervous buy 5 tubes, then just sell off what you don't need.
I just emailed mouser for 6 tubes from the same batch that should give me 150 pieces.
Thanks for your help
